Power Piping (Steam power generating stations, high-pressure boiler plants)
Proper process piping hydraulics requires: Where: )
hf=f⋅LD⋅v22gh sub f equals f center dot the fraction with numerator cap L and denominator cap D end-fraction center dot the fraction with numerator v squared and denominator 2 g end-fraction = head loss (meters or feet)
): Fluid undergoes irregular fluctuations and mixing. Most industrial process piping operates in this regime. 2. Pipe Sizing Criteria and Velocity Limits
Fluid flow in process piping is classified using the dimensionless Reynolds Number ( Most industrial process piping operates in this regime
